Duet 2 Maestro is a latest generation 32-bit open source 3D printer controller board, co-designed by the Duet3D and M3D teams. It serves as a conductor directing the movement of your 3D printer, which is why we call it the Maestro. Feature highlights include five-axis motion control via Trinamic TMC2224 “Quiet Movement” stepper motor drivers with 256 microstep resolution, 120MHz ARM M4 processor, USB and ethernet interfaces, and an ecosystem of pre-existing add-ons and future expansion opportunities. The Maestro comes ready to run your 3D printer or other machine control project using the well-established, open source RepRapFirmware.
